The ethanol fermentation process using beet molasses as the feedstock has been studied. The fermentation process coupled with a membrane separation unit (Pervaporation) was compared to a conventional batch process. Ethanol was produced by Saccharomyces Cerevisiae and recovered by pervaporation using a composite polydimethylsiloxane (PDMS) membrane with 10 µm thickness and 0.0132 m2 area. Initial sugar concentration was adjusted to 60 gr/l and fermentation lasted for 120 hours.
Sugar consumption, ethanol production and cell growth also Flux and Selectivity of membrane was measured by time passage. Sugar consumption rate and ethanol production yield both in the coupled system were higher than those in conventional batch process. Maximum conversion of sugar in coupled system was %94 and a %86 of sugar conversion achieved in conventional batch process.
